非经典近临界流体相态行为的研究

NONCLASSICAL PHASE BEHAVIOR OF FLUIDS IN THE NEAR CRITICAL REGION

对近年来发展起来的非经典近临界相态研究从工程实用的角度作了系统的综述.对这一相平衡领域前沿课题的研究动态及趋势作了讨论.指出近临界区流体相态还远未成熟.经典的状态方程仍占主导地位.但是随着非经典近临界理论的飞速发展,其在工程实际中将会得到应用.

This paper reviews the nonclassical phase behavior of fluids in the near-critical region. This is a field in which a great activity and a considerable progress have occured in recent years. The discussed topics include scaled equations of state and crossover theory. The application of nonclassical phase equations of state in engineering is analyzed.
